IMPROVEMENT IN SHOE-NAILS.

Specification forming part of Letters Patent No. 171,043. dated December14, 1875; application tiled September `18, 1874.

To all whom it may concern:

Be it known that I, DANIEL D. G. PILLS- BURY, of Lynn, Essex county,Massachusetts, have invented an Improved Nail for Heels of Boots andShoes, of which the ibllowing body of the sanne, and, at the same timefavoid injury to the stock of such outer lift; and, in carrying out myobject, I reduce a small portion of the head-end of the nail to a wedgeshape, and create in one or more sides of the head thus reduced a seriesof teeth or indentations, to take a firm hold of the leather and resistpowerfully any tendency to remove the outer lift, in which such head isimbedded.

Inl the drawings accompanying this specification, A represents the nailembodying my improvement, in which the shank or body of such nail isshown at a.

In carrying out my invention, I reduce two sides of the head end of thenail to such an extentas to produce awed ge form, b, of greater or lessacuteness, according to circumstances, thevend of the Wedge beingreduced to suiiciently near a sharp edge to enter or` cut its Way intothe leather Without bruising or crushing the stock, as now results inmany instances.

In reducing or flattening the two sides of the head of the nail, asstated, such head is expanded in the opposite direction, and this aidsvery materially in confining the lift in place, as the bers of theleather will part and yield sufticiently to allow the head to enter andwill then tightly close about it.

Upon one or more sides of the head of the nail .thus formed I impress orcreate several teeth or indentations c c, &c., and when the outer liftis driven upon such heads, the teeth bury themselves in the leather andetlectually resist all reasonable effort to detach it.

I claim- A nail, having a toothed or indented head tapered or reduced toa point or edge at its outer end, as and for the purposes shown and setforth.
